That Southern New England has so many kinds of trees helps explain much of its ecological richness. Oaks are among the most common. I always thought of them as rather boring, especially because their leaves turn blandly brown in the fall and tend to hang on until spring. (I do have fond memories from childhood of tree houses in them and acorn fights.) But Douglas W. Tallamy, an entomologist at the University of Delaware, talks up oaks in his new book, The Nature of Oaks: The Rich Ecology of Our Most Essential Native Trees.

Mr. Tallamy explains how oaks support more life-forms than any other North American tree genus. They provide food (especially acorns and caterpillars) and protection for birds, mammals (consider squirrels,  racoons, bears and bats), insects and spiders, as well as enriching soil, holding rainwater and cleaning the air. And they can live for hundreds of years.

“There is much going on in your yard that would not be going on if you did not have one or more oak trees gracing your piece of planet earth,” he writes in the book, which shows us what’s happening within, on, under, and around these trees.

Mr. Tallamy offers advice about how to plant and care for  oaks, and information about the best oak species for your area.

Hug your oak trees and/or plant some. (And if they get uprooted in a storm, they make about the best firewood.) Fewer lawns, more oak trees, please. Now that it’s April, those remaining ugly brown leaves from last year will soon be pushed out and we’ll soon be enjoying the shade under oaks’ expansive canopies.
